额定压力 – 所采用的阀门只能够用在阀门所标注的针对阀门等级额定值和阀体/阀帽材料的 ANSI 压力-温度额定值的 设计条件范围内(参阅技术参数章节)。
RATINGS – Valves must only be used in design conditions within the appropriate ANSI pressure-temperature ratings for valve class rating and body/bonnet material (see Technical Data section).

材料和应用 – 压力密封阀门具有宽广范围的阀体/阀帽材料和阀内件供用户选择。特殊的材料应该与应用场合相兼容。 MATERIAL AND SERVICE – Pressure Seal valves are available in a variety of body/bonnet materials and trims. Specified materials should be compatible with the service.
产品概述 Product Overview
美国太平洋阀门
选型 Selection
阀门种类和通径 – 为计划应用的领域选择最适合的阀门种类(闸阀，截止阀，或者止回阀)。闸阀和截止阀具有各种楔 形闸板或阀瓣和阀体的配置，适用于不同的应用场合。可以根据现存的管道来确定阀门的通径，也可以根据实现最长使用 寿命的流体条件来确定通径。
闸阀 GATE VALVES
1. 闸阀通常用于启闭应用场合。不适用于节流应用场合。 Gate valves are normally used for on-off service. They are not recommended for throttling service.
温度局限 – 阀门只能够在其结构温度局限范围内使用。阀体/阀帽材料的局限，阀内件、螺栓和填料及垫圈的温度局限， 全都必须考虑到。如果需要，也可以提供特殊结构的、具有更广泛温度局限范围的阀门。
TEMPERATURE LIMITATIONS – Only use valves within the temperature limitations of their construction. Temperature limitations of body/bonnet materials, trim, bolting and packing and gaskets must all be considered. Special construction for extended service temperatures are available on application.

TYPE AND SIZE – Select the best type of valve for the intended service (gate, globe, or check). Gate and globe valves are available with a selection of wedge or disc and body configurations for different services.Valves may be sized to match existing lines, but they should also be sized according to flow conditions for maximum service life.
